Every community that has been around long enough develops a cancerous split between newfags and oldfags at some point. For 4chan everyone would agree 2006 is the cutoff point when newfags/cancer started arriving. For older sites like gamefaqs and arstechnica you have dinosaurs with join dates from the 1990s who look down on latecomers. Before them you have the OGs from the Usenet era who think anyone using the internet after the onset of commercial ISPs is a newfag.

SC2 Mafia is relatively recent but the community has obviously changed a lot and most of the people who were around 5 years ago are no longer active. What do you consider an "oldfag" for SC2Mafia? 2011? 2010? People who played the warcraft 3 map?
